I've got a barcode scanner, which is running well with a Node-RED application based on ctrlX CORE. Here the setting of the serial node:
-> /dev/ttyACM0 is used and this works fine
I tried to access the USB device within the plc application, but with no success. I tried with the following example from this thread: /ctrlx-plc-ctxo5cm7/post/usb-rs232-adapter-KFAWYCAjxEls7w9
Could someone help?
